TL;DR: High-resolution cellular based measurements of wood formation dynamics in three coniferous forest sites in northeastern France are presented and it is suggested that forecasted changes in the annual cycle of climatic factors may shift the phase timing of stem size increase and woody biomass production in the future.
Journal ArticleDOI
Fine root biomass in relation to site and stand characteristics in Norway spruce and Scots pine stands
TL;DR: Variations in fine root biomass of trees and understory in 16 stands throughout Finland were examined and relationships to site and stand characteristics determined, suggesting that more fine roots are needed to maintain a certain amount of foliage when nutrient availability is low.
Journal ArticleDOI
Radial growth variation of Norway spruce (Picea abies (L.) Karst.) across latitudinal and altitudinal gradients in central and northern Europe
Harri Mäkinen,Pekka Nöjd,Hans-Peter Kahle,Ulrich Neumann,Bjørn Tveite,Kari Mielikäinen,Heinz Röhle,Heinrich Spiecker +7 more
TL;DR: In this article, regional and temporal growth variation of Norway spruce and its dependence on air temperature and precipitation were compared in stands across latitudinal and altitudinal transects in southwestern and eastern Germany, Norway, and Finland.
Journal ArticleDOI
Fine root foraging strategies in Norway spruce forests across a European climate gradient
Ivika Ostonen,Heljä-Sisko Helmisaari,Werner Borken,Leho Tedersoo,Leho Tedersoo,Mai Kukumägi,Mohammad Bahram,Antti-Jussi Lindroos,Pekka Nöjd,Veiko Uri,Päivi Merilä,Endla Asi,Krista Lõhmus +12 more
TL;DR: There was 19% higher proportion of root tips colonized by long-distance exploration type forming EcM fungi in the southern forests indicating importance of EcM symbiont foraging strategy in fine root nutrient acquisition and the importance of complex studies on respective regulatory mechanisms in changing climate.
Journal ArticleDOI
Pattern of xylem phenology in conifers of cold ecosystems at the Northern Hemisphere

TL;DR: The findings demonstrated the uniformity of the process of wood formation and the importance of the environmental conditions occurring at the time of growth resumption under warming scenarios, which might lengthen synchronously in the cold biomes of the Northern Hemisphere.
